EDIT: The only other file is the urd.
Linked files within the urd might be a problem if their absolute path is different on the new machine.
When Linking files, UR will use an absolute path for files outside of the UR data path, or relative pathes for files within the UR data path.
I don't know how synced Folder will behave.
